They have a well made but thin outer core and no protection which looked like it could snap if hit. aircraft hose on the other hand has a Teflon core with a use temperature of 280°C is covered with steel braid for runway brush and is very tough and costs the same. My thoughts are; stick with what was designed for aircraft. the Aeroquip 666 is the recommended material by the major brake manufacturers. Scott
